A Technical Guide to Granite Surface Finishes: Engineering Texture and Performance


Image

In both commercial and residential construction, granite’s versatility lies not only in its mineral composition but in the precision engineering of its surface finish. Each finish gives granite unique optical and mechanical properties that make it suitable for specific architectural needs.

Aravali India Marbles & Granites applies precision finishing processes aligned with global quality norms to achieve durable, functional, and aesthetic results. Whether it’s a high-gloss interior surface or a non-slip exterior texture, every finish is designed to enhance strength, safety, and beauty.

High-Gloss Polished Granite for Elegant Interiors


Technical Characteristics:
Surface Roughness (Ra): ? 0.2 µm
Gloss Level: > 90 GU
Processing: Multi-stage diamond abrasive polishing up to 12,000 grit
Applications: Interior flooring, countertops, wall cladding, reception areas

Polished granite has a mirror-smooth surface created through fine mechanical abrasion and high-grit polishing. Ideal for indoor environments, polished granite combines elegance with easy maintenance and stain resistance.

Matte Granite Surface for Contemporary Designs


Technical Characteristics:
Surface Roughness (Ra): 1–3 µm
Gloss Level: 20–40 GU
Processing: Medium-grit progressive polishing without final buffing
Applications: Commercial flooring, wall cladding, stairs, corridors, bathrooms

Honed granite provides a matte or satin finish with minimal reflection while maintaining color uniformity.

Flamed Granite Finish – Thermally Textured for Exterior Durability


Technical Characteristics:
Surface Roughness (Ra): 15–30 µm
Gloss Level: < 5 GU
Processing: Oxy-acetylene flame heating (~1350°C) followed by quenching
Applications: Outdoor paving, exterior cladding, pool decks, walkways

Flamed granite is produced by subjecting the surface to high heat, causing differential mineral expansion that results in a rough, anti-slip texture.

Soft-Touch Granite Surface with Warm Appeal


Technical Characteristics:
Surface Roughness (Ra): 5–10 µm
Gloss Level: 10–20 GU
Processing: Brushed with diamond abrasives after honing
Applications: Countertops, vanity tops, accent walls, outdoor furniture

This surface provides a natural look with low sheen and high grip, making it popular in kitchens, bathrooms, and semi-exterior spaces.

Bush-Hammered Granite – Heavy-Duty Finish for Grip and Durability


Technical Characteristics:
Surface Roughness (Ra): 20–50 µm
Processing: Pneumatic hammering using multi-point carbide tips
Applications: Exterior paving, stair treads, plazas, industrial flooring

Bush-hammered granite has a coarse, pitted texture created by controlled mechanical impact.

Sandblasted Granite Finish – Fine Texture with Matte Uniformity


Technical Characteristics:
Surface Roughness (Ra): 10–20 µm
Processing: Impact of silica or steel grit under compressed air
Applications: Façades, monuments, memorials, public installations

Sandblasted granite creates a soft, even texture with low reflection and consistent grain.

Shot-Blasted Granite Finish – Industrial Durability and Grip


Technical Characteristics:
Surface Roughness (Ra): 15–25 µm
Processing: Steel shot blasting for uniform abrasion
Applications: Driveways, ramps, transport terminals, high-traffic pathways

Shot blasting gives granite a slightly rougher and more uniform texture than sandblasting, resulting in high slip resistance and superior durability.

Waterjet Granite – Clean Surface Engineering for Façades


Technical Characteristics:
Surface Roughness (Ra): Adjustable 5–25 µm
Processing: High-pressure water erosion for surface texturing
Applications: Designer façades, custom textures, architectural panels

It ensures consistent texture and enhances coating adhesion, making it ideal for advanced architectural and composite material applications.

Rock-Faced Granite Finish – Natural Edge, Structural Expression


Technical Characteristics:
Surface Roughness (Ra): Variable (25–60 µm)
Processing: Manual or mechanical chiseling of edges
Applications: Boundary walls, façades, retaining walls, rustic exteriors

It retains structural strength while adding a raw, natural aesthetic to buildings, commonly used in heritage restorations and rustic-style architecture.

Lappato (Semi-Polished) Granite Finish – Hybrid Gloss for Modern Interiors


Technical Characteristics:
Surface Roughness (Ra): 0.5–2 µm
Gloss Level: 40–70 GU
Processing: Partial polishing of raised areas with fine abrasives
Applications: Indoor flooring, wall cladding, commercial lobbies

Lappato or semi-polished granite features a mix of matte and glossy sections, creating a balanced interplay of light and texture.

How to Choose the Right Granite Finish



For Indoor Flooring: Choose Polished or Honed finishes for smooth texture, visual brilliance, and ease of maintenance.

For Outdoor Paving: Opt for Flamed or Bush-Hammered finishes that offer superior slip resistance and weather durability.

For Countertops: Use flamed granite finish Polished or Leathered granite for stain resistance, low porosity, and a refined aesthetic.

For Façades and Cladding: Select Sandblasted, Flamed, or Waterjet finishes for UV resistance, visual uniformity, and long-term strength.

For Industrial Flooring: Go with Bush-Hammered or Shot-Blasted finishes for high friction, wear resistance, and load endurance.
